Description

Technical Field

[0001] This utility model relates to the field of crosshead welding technology, specifically a welding device for Babbitt alloy on the surface of a crosshead. Background Technology

[0002] As a key connecting component in large reciprocating machinery, the performance of the crosshead directly affects the reliability and lifespan of the entire machine. In order to reduce friction, improve wear resistance and extend service life, a layer of Babbitt alloy is often welded onto the sliding surface of the crosshead. Babbitt alloy has good embedding, compliance and anti-galling properties, making it an ideal bearing material.

[0003] Currently, Babbitt alloy welding of crosshead surfaces largely relies on traditional manual welding or semi-automated equipment. In practice, the following technical challenges exist:

[0004] 1. Clamping and positioning difficulties: There are many types of crossheads with different sizes, lengths and diameters. Existing fixtures often have poor versatility and are difficult to adapt to workpieces of different specifications quickly and accurately. Unstable clamping not only affects welding quality but may also cause safety risks. At the same time, it is difficult to achieve stable and centered clamping for irregular cylindrical crossheads.

[0005] 2. Inconvenient adjustment of welding position: In order to ensure that the Babbitt alloy layer evenly covers the entire sliding surface, the angle of the crosshead needs to be constantly adjusted during the welding process. Existing technologies mostly use manual flipping or simple brackets, which have low adjustment accuracy and low efficiency, and it is difficult to achieve precise control of small angles, resulting in poor accessibility of the welding position and easy to have welding blind spots. Utility Model Content

[0006] This invention provides a welding device for Babbitt alloy on the surface of a crosshead. Through the cooperation of the adjustment mechanism and the clamping mechanism, it is highly adaptable and accurately positioned, and can automatically adapt to crosshead workpieces of different lengths and diameters. The bidirectional screw driven by the adjustment motor can precisely adjust the distance between the moving plates at both ends, while multiple clamping blocks independently controlled by clamping cylinders can uniformly clamp the workpiece radially, effectively avoiding inaccurate positioning or clamping damage caused by size differences. It achieves fast, accurate, and flexible clamping. Through the cooperation of the rotation mechanism and the welding mechanism, the welding is flexible and comprehensive, realizing multi-angle adjustment of the workpiece in the clamping state and precise positioning of the welding torch. This allows the welding head to easily reach any position to be welded on the surface of the crosshead, and can complete continuous welding at multiple positions and angles without repeatedly disassembling and assembling the workpiece, significantly improving welding efficiency and the uniformity of Babbitt alloy coating coverage.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a welding device for Babbitt alloy on the surface of a crosshead, comprising:

[0027] Mounting base 1;

[0028] The adjustment mechanism is located on the mounting base 1. The adjustment mechanism includes a control component and a movable plate 14. The control component is located inside the mounting base 1. There are two movable plates 14. Both movable plates 14 are slidably connected inside the mounting base 1 and both movable plates 14 are connected to the control component.

[0029] A rotating mechanism is mounted on two movable plates 14. The rotating mechanism includes a driving component and two rotating positioning disks 10, each rotatably connected to one of the movable plates 14. The driving component is mounted on one of the movable plates 14 and connected to one of the rotating positioning disks 10.

[0030] The clamping mechanism is provided in two sets. Each set of clamping mechanisms is provided on each rotating positioning disk 10. Each set of clamping mechanisms includes a telescopic component and a clamping block 13. The telescopic component is provided inside the rotating positioning disk 10, and multiple clamping blocks 13 are provided on the telescopic component.

[0031] In this implementation scheme: the moving plates 14 move closer or further apart to accommodate crossheads of different lengths. At the same time, the crossheads are clamped by multiple clamping blocks 13 to position crossheads of different thicknesses and achieve the desired effect. The positioning disk 10 is rotated to control the overall angle adjustment of the clamping mechanism, thereby rotating the crossheads and completing welding at different positions.

[0032] Specifically, the control components include a clamping and adjusting motor 16, a clamping bidirectional screw 17, and a limiting rod 3. The clamping bidirectional screw 17 is rotatably connected to the mounting base 1. The clamping and adjusting motor 16 is fixedly connected to one end of the mounting base 1, and the output end of the clamping and adjusting motor 16 is fixedly connected to one end of the clamping bidirectional screw 17. There are two limiting rods 3, both of which are fixedly connected to the mounting base 1. Two moving plates 14 are slidably connected to the two limiting rods 3, and both moving plates 14 are threadedly connected to the clamping bidirectional screw 17.

[0033] In this embodiment, the model of the clamping and adjusting motor 16 can be selected from those available on the market as needed, which will not be elaborated here. The clamping and adjusting motor 16 controls the rotation of the clamping bidirectional screw 17, thereby controlling the relative movement of the two moving plates 14. Furthermore, the clamping and adjusting motor 16 can rotate in both forward and reverse directions, and the limiting rod 3 can restrict the movement of the two moving plates 14, thus completing the use.

[0034] Specifically, the drive components include a steering motor 4, a drive bevel gear 6, and a driven bevel gear ring 5. The steering motor 4 is fixedly connected to one of the moving plates 14, the drive bevel gear 6 is fixedly connected to the output end of the steering motor 4, and the driven bevel gear ring 5 is fixedly connected to one of the rotating positioning disks 10, and the driven bevel gear ring 5 meshes with each other.

[0035] In this embodiment, the model of the steering motor 4 can be selected from those available on the market as needed, which will not be elaborated here. The steering motor 4 controls the drive bevel gear 6 to rotate and transmits power to the driven bevel gear ring 5, so that the rotating positioning disk 10 can rotate within the moving plate 14.

[0036] Specifically, the telescopic component includes a slide groove 7, a clamping cylinder 8, and a slider 9. Multiple slide grooves 7 are provided, and the multiple slide grooves 7 are equally spaced on the rotating positioning plate 10. Multiple clamping cylinders 8 are provided, and each clamping cylinder 8 is fixedly connected to each slide groove 7. Multiple sliders 9 are provided, and each slider 9 is slidably connected to each slide groove 7. Each slider 9 is also fixedly connected to the output end of each clamping cylinder 8. Each clamping block 13 is fixedly connected to each slider 9.

[0037] In this embodiment, the model of the clamping cylinder 8 can be selected from those available on the market as needed, which will not be elaborated here. The slider 9 is controlled to move within the slide groove 7 by the clamping cylinder 8 to complete the clamping and positioning of the crosshead.

[0038] Specifically, it also includes a welding mechanism, which is located in the mounting base 1. The welding mechanism includes a moving part and a welding head 12. The moving part is located in the mounting base 1, and the welding head 12 is mounted on the moving part.

[0039] In this embodiment, the welding head 12 is connected to an external control device to realize the welding of the crosshead. This is an application of existing technology and will not be described in detail here.

[0040] Specifically, the moving parts include a welding adjustment motor 15, an adjustment screw 2, and an adjustment rod 11. The adjustment screw 2 is rotatably connected to the top of the mounting base 1. The welding adjustment motor 15 is fixedly connected to one end of the mounting base 1, and the output end of the welding adjustment motor 15 is fixedly connected to one end of the adjustment screw 2. The adjustment rod 11 is slidably connected to the mounting base 1, and the adjustment rod 11 is threadedly connected to the adjustment screw 2. The welding head 12 is fixedly connected to one end of the adjustment rod 11.

[0041] In this embodiment, the model of the welding adjustment motor 15 can be selected from those available on the market as needed, which will not be elaborated here. The adjustment screw 2 is rotated by the welding adjustment motor 15, so that the adjustment rod 11 can rotate in the mounting base 1, and the position of the welding head 12 can be adjusted for welding.

[0042] In use, place the device on a stable workbench and connect it to an external power supply and air supply. Check that all components are intact. Start the clamping and adjusting motor 16 to control the rotation of the clamping bidirectional screw 17, and control the two moving plates 14 to move closer or further apart on the limit rod 3. Adjust the distance between the two moving plates 14 according to the actual length of the crosshead until they can support both ends of the crosshead. Place the crosshead between the two rotating positioning discs 10, ensuring that the crosshead is approximately centered. Start the clamping cylinder 8 on each rotating positioning disc 10. Each clamping cylinder 8 pushes the slider 9 to slide in the slide groove 7, thereby driving the clamping block 13 to move. Multiple clamping blocks 13 move simultaneously, clamping the crosshead from different directions to adapt to its thickness changes. The clamping force should be uniform to avoid damaging the surface of the crosshead. The steering motor 4 controls the rotation of the drive bevel gear 6, which meshes with the driven bevel gear ring 5, thereby driving one of the rotating positioning discs 10 to rotate. Two rotating positioning discs 10 are linked by a crosshead, and the other rotating positioning disc 10 will also rotate accordingly, so that the crosshead rotates to the required welding position to achieve welding at different positions. The welding adjustment motor 15 is started to control the adjustment screw 2 to rotate. The adjustment rod 11 is threadedly connected to the adjustment screw 2 and slides in the mounting base 1, thereby driving the welding head 12 to move. The welding head 12 is precisely adjusted above the area to be welded by the crosshead, ensuring that the welding head 12 is aligned with the welding point. The welding head 12 is started by the external welding control equipment to start the Babbitt alloy welding process. During welding, the position of the welding head 12 and the angle of the crosshead can be finely adjusted in real time as needed to ensure that the welding covers the entire surface or a specific area. After welding is completed, the welding head 12 and the external equipment are turned off, and the clamping cylinder 8 is operated in reverse to release the clamping block 13 from the crosshead. The welded crosshead is taken out, and the device is cleaned to prepare for the next use.

[0043] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
